iFi Audio iDefender Plus

Break the loop

When plugged into the source device’s USB socket, the iDefender+ detects whether there is a ground loop problem. It breaks the ground loop by ‘intelligently’ disconnecting the computer’s earth and, as well as eradicating audible ground-loop hum, it lowers the system noise floor, improving resolution and dynamic contrast.

Using a USB DAC

The iDefender+ offers an additional benefit. If an external power supply is plugged into the USB-C socket on its side, it blocks power from the computer and instead feeds the DAC with ‘clean’ power from the external supply.

New and improved

We’ve upgraded the circuitry; low-ESR tantalum capacitors have been added for improved input and output filtering. Filtering capacitance has been increased 10-fold.

USB 3.0 SuperSpeed

‘SuperSpeed’ USB 3.0 has a more exhaustive wiring specification which allows for a greater amount of audio transfer while still being backwards compatible. The units incorporate high-quality gold-plated connectors for optimal signal transfer.
